Illustrate a picture from my concepts provided

I'll provide the concept (see attachment and description)...and you bring your skills to bring it to life

I'm looking to make an illustration similar in concept to 'Example from Etsy.png', with 2 people sitting on a rug. I'm not looking for a copy...I'm just sharing to make it easier to explain my concept.

I'd like to:
- change each face (I'll provide a picture of the individual faces to be illustrated)
- change the female to a male (similar clothing to the guy)
- replace the 2 cats with another animal (I'll provide an example illustration
- replace one dog with another animal.

I'm wanting to maintain all rights to the completed artwork.

Please ask any questions as you see fit.
